CGETF2_NOPIV computes an LU factorization of a general m-by-n matrix A without pivoting.
The factorization has the form A = L * U where L is lower triangular with unit diagonal elements (lower trapezoidal if m > n), and U is upper triangular (upper trapezoidal if m < n).
This is the right-looking Level 2 BLAS version of the algorithm.
This is a CPU-only (not accelerated) version.
